Description
Technical field
The present invention relates to a kind of preparation method of artificial tooth, specifically a kind of PEEK composite material suitable for 3D printing is artificial
The preparation method of tooth belongs to dentistry medical material preparation technical field.
Background technique
With the development of digitlization and informationization technology, oral cavity dentistry field of planting has been introduced large quantities of to some extent
High-tech digitizer such as radioactive ray CBCT scanning, the plantation of CT three-dimensional reconstruction, computer virtual, oral cavity model scanning, calculates
The application of the digitizing techniques such as machine Computer Aided Design/auxiliary manufacture (CAD/CAM) is gradually popularized in China big and medium-sized cities, is digitized
Technology helps to improve the efficiency and quality of dentistry plantation, advances the development of tooth-implanting significantly.
3D printer technology is to rely on information technology, material science and precision by one kind based on digital model file
The multi-disciplinary sophisticated technology such as machinery mainly passes through CAD (CAD) Software Design Model data, by data
Specific printer is imported, with the fusible jointing material such as powdery metal or plastic, is successively beaten by heating melting extrusion
The mode of print constructs object.3D printing technique has gradually been applied in each field of clinical oral, in dentistry field of planting, 3D at present
Printing can be used for rapid shaping individual character according to CT scan data or the planting body of Computer Design model manufacturing any shape
Change artificial tooth.
Artificial tooth is mainly made of titanium at present, its advantage is that high mechanical strength, but titanium-based artificial tooth deposits biology
The disadvantages of poor activity, elasticity modulus is excessively high and metal ion is precipitated, therefore, the present invention wish to prepare a kind of mechanical strength and
The more good nonmetallic materials artificial tooth that bioactivity has both.
Polyether-ether-ketone (PEEK) is a kind of plastics with high intensity, high-fracture toughness, and fatigue durability can be equal to alloy
Beauty.Medical grade PEEK has good biocompatibility, no cytotoxicity, no mutagenicity, non-carcinogenesis, does not cause allergy, also
With extremely strong corrosion-resistant, hydrolysis and chemical resistance, and it is with good mechanical performance, is to study at present more wide
One of general artificial bone and artificial teeth material.PEEK is used alone as artificial teeth material, its shortcoming is that lacking osteogenic induction
Function.The inorganic part of hydroxyapatite (HA) and people's bone and tooth has similar chemical composition and structure, has good bone
Conductibility is ideal biomaterial.The HA of crystal whisker-shaped can absorb energy by the bridge joint of whisker, crack deflection and extraction effect
Amount eliminates crack tip stress, makes stress in whisker by load transmitting, answers suffered by surrounding matrix material to reduce
Power achievees the purpose that enhance biomaterial intensity, therefore a certain proportion of HA whisker is added to the PEEK being compounded to form in PEEK
Composite material can be used as the material for preparing artificial tooth well.In addition, the composition and crystallinity of artificial synthesized HA and natural bone
Difference, natural bone is a kind of typical calcium-deficient apatite, therefore there is slow, self-bone graftings of degrading as implantation material by HA
The relatively low deficiency of property, it is often necessary to which some members are added in HA usually to be improved its performance, and is mixed barium hydroxyapatite (Ba-HA) and is exactly
One kind modified HA material therein, the addition of Ba can replace the part Ca in HA, so that the lattice of HA is distorted, thus plus
Its fast degradation speed simultaneously increases its osteoinductive, and in addition the addition of Ba, which can also be played the role of hindering, penetrates x-ray.
Since the fusing point of PEEK material is high, viscosity is big, at present on the market can be using PEEK as the 3D printer of printed material
Seldom, the Apium M series 3D printer of German Apium company production is the 3D printer of profession printing implanted medical device,
It has many advantages, such as that heating temperature is high, sprinkler pressure is big, print resolution is high, be applicable to PEEK, fibre reinforced PEEK,
A variety of high performance high molecular materials such as PEI 9085, POM-C, and PEEK material is handled using it, it will not influence PEEK material
The biocompatibility and bactericidal property of material, thus it is particularly suitable to the present invention.
In addition, the present invention is in order to increase osteoinductive and bioactivity, it is also necessary to what is printed by 3D printer
PEEK composite material artificial tooth is further surface-treated.
Summary of the invention
